Abstract
Introduction: The knowledge of the neurovascular relationships of the infratemporal region is relevant in dentistry and surgery.
Aims and objective: To study the variations of nerves and maxillary artery in human cadavers through infratemporal dissection. The branches from the posterior division of the mandibular nerve studied and analyzed for abnormal course and branches.
Material and method: 85 human cadavers were dissected and studied.
Result: A rare type of bilateral communication between the auriculotemporal and inferior alveolar nerve is reported in this study. This communicating nerve is neither related to maxillary artery which is superficial to lateral pterygoid muscle in this case, nor it is related to origin of mylohoid nerve (these type of variations are described in most of the previous studies).Other variations are deep course of maxillary artery, variations in origin of nerve to mylohyoid etc.
Key words: dental surgery, inferior alveolar nerve, infratemporal fossa, lingual nerve, maxillary artery.
